Abstract
Shelving including a flat shelf member positioned on corner posts, where the height is adjustable. Each of the corner posts has a spiral indentation around its exterior. Corner clamping assemblies are placed about each corner post. The clamping assemblies have frusto-conical shaped exteriors and are provided on their interior with an inwardly extending protrusion which can engage within the spiral indentation. The shelf has corner retaining members with complementary frusto-conical interiors which receive and securely hold the clamping assemblies about their respective corner posts. The spiral indentation in the corner posts permit the corner clamping assemblies to be positioned at any location along the corner posts to thereby selectively vertically position the flat shelf at a desired height. In a modified embodiment, each corner post is provided with two equally spaced spiral indentations around its exterior, so that each corner clamping assembly may include two separate identical members each provided with at least one protrusion on its interior wall. Preferably, a locating mark is disposed vertically on each corner post across the spiral indentation for positioning the corner clamping assemblies in alignment with each other.
